Product Description
The Canon FD 2X-B Extender is a teleconverter designed to double the effective focal length of compatible Canon FD-mount lenses (for lenses of 300mm or shorter focal length). It mounts between the lens and camera body and retains automatic diaphragm coupling so that AE (auto-exposure) functionality is preserved with suitable cameras and lenses. Using this extender results in a loss of two stops of light, and though the master lens’s minimum focus distance remains unchanged, effective magnification increases. It’s an excellent tool for reaching further without carrying a longer lens, particularly useful for wildlife, sports, or distant subjects.
